Question

I have this line in my CSS:

.ui-icon-zoom-in { content: url(images/16x16/ZoomIn.png); } 

Which I am using with jQuery UI Button widget li

Answer 1

One can use the box-sizing property to keep the dimensions, addind the new image as background image and pushing "out" the existing (old) inline-image by padding-left:

.image{
  -moz-box-sizing: border-box;
  box-sizing: border-box;
  background: url(https://yourdomain/yoursite/yourasset.png) no-repeat;
  width: 20px; /* Width of new image */
  height: 25px; /* Height of new image */
  padding-left: 20px; /* Equal to width of new image */
}

box-sizing has a good webbrowser-support: https://caniuse.com/#feat=css3-boxsizing
